Fire ValidateLabelEdit when new node text has not changed?


My users can add new nodes to a tree, and I add new nodes with a default name "New Node" and put the node in edit mode so the user is urged to rename the new node.  I use the ValidateLabelEdit event to ensure the name is unique in the tree.

However, if the user adds a new user but doesn't change the name, the new node in the tree is called "New Node".  Which means when a second new node is added and the user doesn't change the name, a duplicate exists.

The problem I have is that the ValidateLabelEdit event doesn't fire.  How can I make the ValidateLabelEdit event fire when the user hasn't modified the tree node name?
